5 days ago · In quantum mechanics, an atomic orbital ( / ˈɔːrbɪtəl /) is a function describing the location and wave-like behavior of an electron in an atom. [1] . This function describes the electron's charge distribution around the atom's nucleus, and can be used to calculate the probability of finding an electron in a specific region around the nucleus. [2]
2 days ago · A photon (from Ancient Greek φῶς, φωτός (phôs, phōtós) 'light') is an elementary particle that is a quantum of the electromagnetic field, including electromagnetic radiation such as light and radio waves, and the force carrier for the electromagnetic force. Photons are massless particles that always move at the speed of light measured in vacuum.
